More than 50 people, including two peacekeepers from the UN, have died in a big fight at the border between South Sudan and Sudan, according to officials.
Men with weapons from Warrap State in South Sudan attacked the Abyei region on Saturday, according to Abyei information minister Bulis Koch. Reuters news agency reported this.
The reason for the attack is not known, but the Associated Press news agency said that the fighting was connected to a dispute over land between the Twic Dinka and Ngok Dinka ethnic groups.
South Sudan and Sudan both say Abyei belongs to them. They have been arguing about it since South Sudan became its own country in 2011.
The UN force in the area, also called Unisfa, said a peacekeeper from Ghana was killed on Saturday when their base was attacked.
A Pakistani peacekeeper died on Sunday when UN troops were attacked while taking injured people to the hospital.
The UN said that local officials reported 52 people were killed and 64 were badly hurt in the battle.
